Democratic governor candidate Jeff Greene, who has been largely invisible in the final days of the primary campaign, said Monday he hasn’t given up even though his campaign announced he was canceling his election night watch party.

“We’re not throwing any towels in,” he said in a telephone interview. “I know the polls are showing us down. The Gravis poll shows us No. 2 behind Gwen. I’m hoping that our ground game, which has been much, much, much stronger than hers ... I’m hoping that will make the difference despite what some of these polls say, we’re going to pull this out and win.”

He was referring to a Gravis Marketing survey that showed Gwen Graham with 26 percent and Greene with 19 percent.

Greene, a billionaire, had scheduled a primary night party at a hotel he owns, the Tideline Ocean Resort & Spa in Palm Beach.

On Monday, the campaign said, he would watch the results from home — an announcement that generated a flurry of online discussion about the implications.

Greene maintained canceling the party at the hotel doesn’t mean he expects to lose. Instead, he said he’d rather watch the results from his home in Palm Beach with his wife, children and a few friends. He said that would allow for a more relaxed atmosphere.

“I kept thinking ‘How do we do this at the house?’ ” he said during a phone interview as he headed north after a Miami campaign stop — driving his Tesla and looking for a charging station at the Delray Marketplace in southern Palm Beach County.

“The way I really want to spend [Tuesday] night, to tell you the truth is to be in my jeans,” he said. “My preference has always been to be with my wife and three kids.” The hotel, he said, is “not as comfortable as being with all the team in my living room with the kids around.”

And, he said, having a party at his home would allow him to say a better thank you to his campaign staffers who have been working long hours during the campaign. “Everyone’s worked morning till night without a day off for months,” he said.

The only reason to do it at the hotel, he said, was to accommodate the news media.

Greene didn’t get into the race until June 1 — and briefly upended the contest in which Graham, Andrew Gillum, Philip Levine and Chis King had been running for more than a year.

He surged in public polls after spending millions on TV ads. Almost all the $38 million in Greene campaign spending has come from his own pocket. To put that in perspective, he reported a net worth of $3.3 billion on the financial disclosure he filed with the state in June.

Last week, after polling suggested his candidacy had stalled, he stopped all TV advertising.

On Friday, he announced he’d go back on the air — with a miniscule ad buy in three of Florida’s 10 media markets.

On the final Sunday of the campaign, when the other candidates were targeting key constituencies in either South Florida (Gillum and Levine) or Central Florida (Graham and King), Greene’s campaign didn’t put out a schedule of public events.

As of Monday afternoon, he hadn’t posted any pictures on Twitter of himself at any campaign events since an Aug. 21 appearance at the Broward Democratic Party.

Greene said the campaign has been focused on turning out supportive voters. He said phone banking had found 350,000 supporters, and his campaign is trying to make sure they vote.

He said he had a busy day on the campaign trail Monday, when he visited Jacksonville, Orlando and Miami. He said he’s also been visiting campaign offices and had more stops planned for the evening. “We’re kind of bounding around,” he said.
